59 yo, old time static and old time model maker in my spare time. After some 30 years experience with 2D CAD, I never felt the professional need to go 3D and besides the user interfaces and methods were horrible. When I took the decision to gone on a totally different direction and be my own boss I selected SU in Oct 14 in order to avoid the not-another-degree! syndrome. But I was wrong.Simple on the surface, but deeper as you dig!
